Abstract

An electro-acoustic transducer is oriented such that its transducer axis is parallel to, and in, the plane of a baffle coupled to the electro-acoustic transducer for reduced baffle vibration.

Claims

AMENDED CLAIMS [Received by the International Bureau on 24 April 2008 (24. 04. 2008)]
1. An apparatus (120, 220, 320, 420) comprising: a baffle (180, 280); an electro-acoustic transducer (110, 210, 310, 410, 510, 710) characterized by a transducer axis (115, 215, 315, 415); and a housing (170, 270, 330, 430, 530, 730) supporting the electro-acoustic transducer (110,
210, 310, 410, 510, 710) at an orientation such that the transducer axis is parallel to a plane characterizing the baffle, the housing and baffle separating a listening area from a cavity, wherein the transducer axis is displaced from the baffle plane by a distance that is less than a radius characterizing a size of the electro-acoustic transducer.
2. The apparatus (120, 220, 320, 420) of claim 1 wherein the baffle (180, 280, 380, 480) is selected from a group consisting of a room wall, a room ceiling, a vehicle door panel, a vehicle rear package shelf, or a vehicle instrument panel.
3. The apparatus (120, 220, 320, 420) of claim 1 wherein the baffle (180, 280, 380, 480) is an interior door panel of a vehicle.
4. The apparatus (120, 220, 320, 420) of claim 1 wherein the transducer axis (115, 215, 315, 415) is in the plane characterizing the baffle.
5. The apparatus (120, 220, 320, 420) of claim 1 wherein the housing is an enclosure (330, 430, 530, 730).
6. The apparatus (120, 220, 320, 420) of claim 5 wherein the enclosure (330, 430, 530, 730) is sealed.
7. The apparatus (120, 220, 320, 420) of claim 5 wherein the enclosure (530, 730) is mounted to an inner door panel (590).
8. The apparatus (120, 220, 320, 420) of claim 5 wherein the enclosure (530, 730) is mounted to a vehicle door frame.
9. The apparatus (120, 220, 320, 420) of claim 5 wherein the enclosure (530, 730) is mounted
AMENDED SHEET (ARTICLE 19) to a vehicle door trim panel.
10. The apparatus (120, 220, 320, 420) of claim 5 wherein the enclosure (330, 430) is mounted to a wall stud.
11. The apparatus (120, 220, 320, 420) of claim 1 wherein the enclosure (430, 730) includes an acoustic element (435, 750) acoustically coupling an enclosure volume to a listening area (420).
12. The apparatus (120, 220, 320, 420) of claim 11 wherein the acoustic element (435, 750) is a port.
13. The apparatus (120, 220, 320, 420) of claim 11 wherein the acoustic element (435, 750) is a passive radiator.
14. The apparatus (120, 220, 320, 420) of claim 13 wherein a radiator axis characterizing a movement of the passive radiator is parallel to the transducer axis (415).
